UNITED STATES PATENT "OFFICE PRODUCTION .OF EIHBOSSED EFFECTS ON. PARCHMENTIZED FABRICS Application December 17. 1938, Serial NoJZdliA In Germany January 5, 1938 7Claims. ((21.154-2) This invention relates to the production of shrinking agent, such as caustic soda lye or embossed eflects on parchmentized fabrics. mineral acid without stretching the doublecloth.

There are quite a number of known methods a compound fabric is obtained the whole parchwhich have for their purpose the production of mentized constituent structure of which is emembossed eflects sometimes called "cloqubossed. In this way a parchmentized cloqueffects on fabrics. Such fabrics can be profabric is obtained.

As adhesives other artificial resinous products insoluble in water, alkali and acid may be used and as back cloths any fabrics maybe employed which can be shrunk by treatment with concentrated caustic soda lye or other alkalies or acids.
